Microfluidic Filtration and Separation

Functional components ensure sample purity for microfluidic diagnostic systems

Successfully Filter and Capture Sample Particulates

Reduced samples and reagent volume, lower costs, and shorter analysis times are just a few of the recent advances in microfluidic systems requiring enhanced analytical performance. High-fidelity multiplex and multiclass assays synergize components and advances in nanotechnology, molecular diagnostics, microfluidics, and microelectronics. These technologies are being developed in new and powerful measurement tools within a small device footprint.

Porex supports all microfluidic device functions and component needs with custom diagnostic solutions designed to meet or exceed the tightest analytical performance requirements. Clinical science products, media, and filters from Porex are engineered to help ensure performance, purity, accuracy, and reproducibility in demanding IVD, molecular and clinical diagnostic sample preparation, liquid handling, and microfluidic applications.
